Explore the connections between engineering and science with KQED’s new, free e-book, Engineering Is Saving the World with Cookstoves. Learn how researchers designed a new, more efficient cookstove to improve the quality of life for families in Darfur.

From KQED Education Do Now: The UK recently voted to authorize mitochondrial DNA modification, which has been dubbed the "three-person embryo" law. Should we modify DNA in human eggs or embryos in order to prevent disease?

California’s Napa Valley has a microclimate that produces world-famous wines, but what happens as the climate warms up? Vintners are using advanced technology to conserve water, while scientists are testing varieties that could replace the cool-climate Pinot Noirs of today.

Energy

Since the Darfur crisis began in 2003, women living in the refugee camps walked for up to seven hours outside the safety of the camps to collect firewood for cooking, putting them at risk for violent attacks. Now, researchers at Lawrence Berkeley National Laboratory have engineered a more efficient wood-burning stove, which is greatly reducing both the women's need for firewood and the threats against them.
